cash and carry EOC problem #2 page 205

There is a cash & carry EOC problem problem #2 page 205 of Derivatives. Why is there is no borrowing to purchase the asset at the spot rate? The very next problem #3 does borrow to fund spot purchase, as do other examples.Am I missing anything here?

Also, on page 187 of Derivatives in Example 2. The equation (100 - 96.09)/400 * 91/90. Where does 400 come from? It is not on the table for Eurodollar futures prices.

the 400 question has been discussed before as well.

it is the 25 bps change on Eurodollars prices per tick.

1/0.0025 = 400
